if we are talking about LaTeX, then properly done writes to files
(AUX, etc) - those using standard LaTeX commands to do writes - will
save the characters properly in LaTeX internal character
representation (LICR) form, even when you are using UTF-8 input
encoding, e.g. if Á (in UTF-8 encoded document) will be written to a
file, it will be represented in the encoding-independent form: \'A
the characters in AUX and other files written by TeX should be
encoding-independent, as the document can use several input encodings,
so writing UTF-8 to files is not a good idea.

these "dirty tricks" are not permitted in LaTeX (even for
macro-package writers) - catcodes of letters (when using inputenc) and
uc/lccodes are fixed.

if one uses proper interfaces (e.g. protected writes in LaTeX) then
there will be no problems.
